Blano’s Diamond Super Single Bowl kitchen sink are made with Silgranit II, a proprietary blend of granite sand and a heavy-duty composite binder.

This material offers the beauty and toughness of solid granite at a much more affordable price point. Plus, Silgranit is far easier to clean and maintain than natural stone–Blanco claims “40% greater cleanability” than other materials.

The granite composite used by Blanco is non-porous and highly stain resistant. It’s also unaffected affected by acidic foods (like wine) that can react with some other materials.

Granite composite is also incredibly tough and durable. With a heat resistance of 536° F, you can go straight from your oven or stove into the sink. Plus, many users reviews report years of use without nicks, chips, or scratches.

3. Elkay Quartz Classic Double Bowl
